DNA Structure and Replication Taylor, Woods and Hughes labeled Vicia DNA by allowing new DNA synthesis in the presence of radioactive thymine. After DNA replication (S phase of the cell cycle), it was observed that both (a) and (b) both chromatids of a chromosome were labeled neither chromatid was labeled only one chromatid of a chromosome was labeled both (a) and (b) both chromatids of a chromosome were labeled neither chromatid was labeled only one chromatid of a chromosome was labeled ANSWER DOWNLOAD EXAMIANS APP
